Answer:
20/n+10 = 10/n+20 n
multiply both side n,
n (20/n+10) = n(10/n+20 n)
20+10n = 10+20n^2
20+10n -20 = 10+20n^2 -20
10n = 20n^2 -10
10n - 10n = 20n^2 -10 -10n
0 = = 20n^2 -10 -10n
20n^2 -10 -10n = 0
n = 1 or n = -0.5
Step-by-step explanation:
Answer:
<h3>The correct answer is <u>D: -30</u></h3>
The answer to the question is 2.)2.5 because when you substitute 12/7 into the inequality you get 20 which is not greater than 20 and when you substitute -3 you get -13 which is also not greater then 20 but when you substitute 2.5 you get 25.5 which is greater than 20
Since the square root of five is approximately 2.24, it would lie in between 2 and 3 on a number line.
